The objective of this research was to evaluate the impact of organic sources (animal manures vs. plant residues at the rate of 10 t ha-1 each) on the productivity of hybrid rice (Oryza sativa L.) production under different levels of phosphorus (0, 30, 60, and 90 kg P ha-1) fertilization. Two separate field experiments were conducted. In experiment (1), impact of three animal manures sources (ca...

to determine the coefficients of c1 and c in mitscherlich-bray equation, critical level and fertilizer recommendation for potassium (k) as by mitscherlich-bray (mb) equation, an experiment in a randomized complete block design of 5 treatments and 3 replications was carried out in 12 irrigated wheat (triticum aestivum l.) fields in sarpol-e-zohab region during the 2007-08 growing season. the tre...

Evaluating agricultural land management practices requires knowledge of soil spatial variability and understanding their relationships. Spatial distributions for fourteen soil physical and chemical properties were examined in a wheat field in Sorkhankalateh district, in Golestan province, Iran. 101 soil samples at the distances of 5m, 10m and 20m as nested grid were collected at the depth of 0-...

Background: Renewable energy (RE) production is a land-use driver with increasing impact on landscape configuration and a matter of controversial debate. Woody biomass cropping provides an opportunity to interlink RE supply with spatial planning goals, RE concepts and rural development programmes since it tackles several issues, ranging from climate or soil protection to over food production an...

A farmer organization policy is studied through the case of Baja California Wheat Product System. The performance committee that represents it evaluated. There no research on these problems in northern Mexico, therefore imperative to document and publish knowledge generated for its understanding over time. With structured interviews construction Problem Trees, causes effects were determined mea...

In many countries, farmer saved seed (FSS) competes directly with a highly regulated commercial industry that sells certified seed. Opponents to the use FSS argue it reduces royalty income for plant breeders and is inferior in quality, which farm profitability. We because farmers have knowledge about field history quality of seed, they can make profit enhancing decisions use, or not FSS. also s...

The loose smut of wheat (Ustilago tritici (Pers.) Jens.) (PI. 1), according to estimates compiled in the Plant Disease Bulletin 3 for the years 1917 to 1921, inclusive, caused an average annual loss to farmers of the United States amounting to more than 11,000,000 bushels. Recommendations for control of this disease in this country have been confined to treatment of the seed by the modified hot...
